Given numbers are 770,639,749,534,254
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,639,749,534,254 is 595071414630.
Find LCM of 770,639,749,534,254 with Prime Factorization
| 2 | 770, 639, 749, 534, 254 |
| 3 | 385, 639, 749, 267, 127 |
| 7 | 385, 213, 749, 89, 127 |
| 55, 213, 107, 89, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 55 x 213 x 107 x 89 x 127 = 595071414630
Therefore, the lowest common multiple of 770,639,749,534,254 is 595071414630.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
770 x 639 x 749 x 534 x 254 = 49985998828920
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
639 : 1, 3, 9, 71, 213, 639
749 : 1, 7, 107, 749
534 : 1, 2, 3, 6, 89, 178, 267, 534
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,639,749,534,254, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
639:3x 3x 71
749:7x 107
534:2x 3x 89
254:2x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 7 = 84
Therefore, the value for common factors is 84.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 49985998828920/(1x84)
LCM = 49985998828920/84
LCM = 595071414630
Thus, we can understand that the LCM of 770,639,749,534,254 is 595071414630.
